While I briefly mentioned the Primus EtaPower MF (multi-fuel) backpacking stove on Day 3 of OR, here's some more information about it and the new integrated canister EtaExpress for all the stove gearheads.

Primus EtaPower MF

Unlike many stoves that call themselves “multi” or “all-fuel,” but really only burn liquid fuels, the EtaPower MF is an actual multi-fuel backpacking stove that will burn any available fuel—butane, propane, diesel, paraffin, or aviation fuel. According to Primus, the EtaPower MF “blends the most fuel-efficient stove design in the world with the convenience of omnivorous multi-fuel technology.” Primus claims its ETA burner design is twice as efficient as average stoves, allowing for faster boiling times, less fuel consumption, a lower total weight, and a more environmentally friendly stove.

The EtaPower MF has a piezo ignitor and comes with a burner stand, windscreen, 2.1 liter EtaPower pot with heat exchanger, and .35 L fuel bottle that nests inside; additional accessories include a frying pan, handle, and bag that doubles as pot insulation. If you don’t need the multi-fuel option, Primus already has the EtaPower EF (easy fuel) out for $80 less. Can’t wait till 2008? You can watch Primus’s online video about EtaPower stoves.

Primus EtaExpress

Built on the same heat exchanger foundation as the EtaPower, the EtaExpress is a compact, 14.7 oz, integrated canister version, designed for the solo traveler. It consists of a lightweight stove (2.9 oz) with piezo ignitor that mounts directly to an LP gas canister, a clip-on wind screen for fuel efficiency, and 1 L pot with fry pan lid. A heat exchanger mounted directly to the pot keeps the flame focused where it's needed, reducing heat loss, maximizing fuel efficiency and lowering boil times. The stove and a 230 g LP gas canister store in the 1 L pot for transport.
